Description:

Blueman and associated programs are python scripts. However, it defaults to using a local python interpreter (if present), making it not uses system dependencies and thus not running/running with different libs than the system (e.g. dbus) which leads to missing libraries and various issues.

Additional info:

I was not sure it falls into feature request/bug request/go ask upstream to do stuff correctly, but an easy fix would be to do just like packages needing python2 without enforcing it, that is change the very first line to force them to use #!/usr/bin/python explicitly instead of #!/usr/bin/env python

Steps to reproduce:

- Have local python install in path, launch from gnome shell or any other desktop manager, nothing happens if local python is missing dependencies.
- Open terminal, launch blueman-*, look at missing dependencies message.

Simple example

samuel ~ $ which blueman-adapters
/usr/bin/blueman-adapters
samuel ~ $ /usr/bin/blueman-adapters
Traceback (most recent call last):
File "/usr/bin/blueman-adapters", line 8, in <module>
import dbus
ImportError: No module named 'dbus'


samuel ~ $ /usr/bin/python /usr/bin/blueman-adapters
/usr/bin/blueman-adapters:10: PyGIWarning: Pango was imported without specifying a version first. Use gi.require_version('Pango', '1.0') before import to ensure that the right version gets loaded.
from gi.repository import Pango
blueman-adapters version 2.0.4 starting

And stuff works from then on.
